Features

The FRIDB realizes an experimental platform for RFID (13.56 MHz). It consists of an Antenna, a ST Micro M24LR64 RFID-Tag Chip with 64kbit EEPROM and I2C port and a Texas Instruments TRF7960 RFID reader chip with SPI interface.

So you can make the Freerunner either a RFID tag (e.g. to open doors) or a RFID reader (to read/write standard tags e.g. in credit card format).

The board comes with three parts that can/must be separated:

Antenna

RFID-Tag with I2C EEPROM (ST Micro M24LR64)

RFID-Reader with SPI interface (TI TRF7960)

Either the Tag or the Reader module fits into the area above the SIM/SD card reader of the Openmoko Freerunner.
The antenna can be fixed by tape instead of the battery cover or mounted externaly.
It is up to you to wire the board to the Freerunner main board in a way that you can still swap SD cards and/or SIM cards.

The FRIDB can also connected to other Microcontrollers and SoC (e.g BeagleBoard) since it has splitted I/O and power supply.

Expansion pads

The supply voltage as well as the SPI / I2C bus is routed to testpads at the end of the board.
